1. Natalia Arendt MY IDEA Thermocouple panel "Saving in harmony with nature"

2. Thermocouple panel the temperature difference on opposite walls of the building envelope (the difference between sunlit and shaded wall can reach tens of degrees Celsius) the difference in temperature outside the building and the ground (eg underground in the basement of the building).

3. Thermocouple panel one thermocouple (wire pair) can be obtained 10μV / K which is to get 24V at 20K temperature difference (° C), use 120 000 thermocouples
